I think it has to do with you installing fonts on your phone. I never had an iphone but it looks like you use custom fonts, judging by the URI-bar on
your iphone.
Your settings are customized but by you is the question. There's the "comic sans" font for the address and title bar. Assume that's on purpose/has
to do with your layout/ general customization.
I've seen similar symbols show on when my pc/ connection was loading slowly before.
